Mild steel foundation bolt is used for light and medium concrete foundations, small equipment bases, photovoltaic support legs, and ordinary steel columns. It can be made in L type, J type, T type, or straight anchor form. The advantage is its stable forming and welding performance: Q235B is easy to bend, thread, and galvanize, so it fits batch production when the drawing needs many sizes with the same surface finish.

Product Advantages
1) Mild steel foundation bolt is suitable for bending into L and J shapes without cracking at the hook area when the radius is made correctly.
2) Q235B can be threaded and galvanized in large batches, which helps keep the nut fit and surface finish consistent.
3) The 4.6 or 5.6 grade option is enough for many light support bases when the load design does not ask for alloy steel.
Main Applications
Used for ordinary building foundations, photovoltaic supports, light machinery bases, fence posts, and small steel columns.
Suitable for projects where low carbon steel and hot-dip galvanizing are specified.
Order Check
Before production, confirm diameter, total length, hook length, thread length, exposed height, and surface treatment.
If the bolt is used with a template plate, the hole spacing should be checked together with the anchor bolt drawing.
Quality Check
Inspection focuses on the dimensions that affect installation, not only the outside appearance.
The checked data can include diameter, hole distance, thickness, thread fit, coating surface, and packing mark.
